Abstract: A tool (22) for initiating a downhole function in a subsurface well (10), su ch as a cased well. The tool has memory adapted to store a well-specific reference pattern of one or more downhole well characteristics as a function of position along the well, one or more sensors responsive to the downhole well characteristics, and a clocked processor. The processor is adapted to receive well characteristic signals from the sensors, determine, from the signals and the reference pattern in memory, the position of the tool along the well, and automatically initiate a downhole function at a preprogrammed position along the well while the tool is moved at a substantially constant rate along the well. The tool may be configured in a string of tools for performing multiple downhole functions. In some embodiments the reference pattern is the known spacing of discrete downhole features, such as casing collars (16). In some other embodiments the reference pattern is a log of a geophysical parameter, such as a natural gamma log. Methods of use are also disclosed.

Abstract: The mechanical lock (10) includes a rod (30) having one end extending into a housing (14) and another end extending out of the housing. The rod translate through bores through bushings (40) within the housing. Coil springs (60, 61) in the housing and surround the rod. When the springs are in their normal orientation, they grip the rod tightly and prevent the rod from translating. The rod and bushings have complementary structure for preventing the rod from rotating within the bushings and housing. In the exemplary embodiment, the structure are flat surfaces (31) along the rod and the bushing that mate with each other.

Granted: 2008-11-18
Abstract: Substrates have a hydrophobic surface coating comprised of the reaction products of a chlorosilyl group containing compound and an alkylsilane. Most preferably the substrate is glass. In one embodiment, highly durable hydrophobic coatings may be formed by forming a silicon oxide anchor layer o r hybrid organo-silicon oxide anchor layer from a humidified reaction product of silicon tetrachloride or trichloromethylsilane, followed by the vapor- deposition of a chloroalkylsilane. Such a silicon oxide anchor layer will advantageously have a root mean square surface roughness of less than about 6.0 nm and a low haze value of less than about 3.0 %. Another embodiment includes the simultaneous humidified vapor deposition of a chlorosilyl group containing compound and a chloroalkylsilane. In preferred embodiments, the simultaneous vapor deposition onto a glass substrate of silicon tetrachlorid e and dimethyldichlorosilane results in a hydrophobic coating comprised of cro ss- linked polydimethylsiloxane, which may then be capped with a fluoroalkylsilane. The cross-linked polydimethylsiloxane layer may be formed on the surface of the glass substrate, or a silicon oxide anchor layer may b e deposited under the cross-linked polydimethylsiloxane layer.

Title: Bituminous froth inline steam injection processing
Inventor: GASTON LES
IPC: B01F33/40
Filed: 2004-01-09
Granted: 2011-04-05
Abstract: An inline bitumen froth steam heater system is comprised of steam injection and static mixing devices. The steam heater system heats and de-aerates an input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The inline bitumen froth steam heater is a multistage unit that injects and thoroughly mixes the steam with bitumen resulting in an output bitumen material having a homogenous temperature of about 190°F. The heating system conditions a superheated steam supply to obtain saturated steam at about 300°F. The saturated steam is contacted with a bitumen froth flow and mixed in a static mixer stage. The static mixers provide a surface area and rotating action that allows the injected steam to condense and transfer its heat to the bitumen froth. The mixing action and the increase in temperature of the bitumen froth results in reduction in bitumen viscosity and also allows the release of entrapped air from the bitumen froth.
